What was the first play ever written?

The first play ever written is considered to be "The Epic of Gilgamesh," which dates back to ancient Mesopotamia (modern-day Iraq) and is believed to have been written around 2100 BC. The Epic of Gilgamesh is a long narrative poem that tells the story of the mythical king Gilgamesh and his quest for immortality. While it is not a play in the modern sense, with actors performing dialogue on stage, it is believed to be the earliest example of a written dramatic work.
